Cannot implicitly convert type 'string' to 'double' Issue

Question

    private void updateButton_Click(object sender, EventArgs e)
    {
        //custID.Text = customers[id].ID.ToString();
        customers[id].Name = custName.Text         


        

Answer 1

You should use Double.TryParse() to convert your string to a Double.You cannot save a string on a Double Datatype and there is no implicit conversion available in c# to do that

Double result;
Double.TryParse(custBal.Text,out result);
